IMPROVEMENT IN STEAM-DRVING CYLINDERS.

Specification forming part of Letters Patent No. 134,786, dated January 14, 1873. t

to the accompanying drawing making a part4 of this specification, in whicl Figure l represents an end sectional view of cylinder, showing the T-iron dividing rib and support, also the troughs or buckets, and the pipe leading to the eduction-spout; Fig. 2 represents an internal View or longitudinal section of drying-cylinder, showing the angular troughs or buckets for conveying the condensed steam from one section to another,

and Fig. 3 is a View of the same in another position-on a quartershowin g the conveyance to the discharge-pipe.

My invention relates to steam-drying'cylinders for" various purposes, so constructed and provided with buckets and other internal arrangements as to eftectually eject the Whole of the water formed by the condensation of the steam in the said cylinders as fast as it condenses, and thus and cooling of the cylinder. My invention consists in a peculiar arrangement of troughs or buckets placed and Xed obliquely to the axis ofthe cylinder between each dividing rib or partition of T-iron. One or more of the buckets are required in each section, according to the diameter ofthe cylinders, as the case may be, so that as the cylinder revolves the said troughs or buckets eject or drain the water from one division to another between the rib's or T-irons until it is conducted to the outj let or nozzle, on which the cylinder revolves at one end, and is discharged.

By this means there is less or noprisk of a collapse of the cylinder through the accumulation of Water by sudden condensation of steam, or of an accumulation of dirt or other substances within the cylinder.

To enable others to make and use my invention, I will describe it more in detail, referring to the drawing and the letters marked thereon.

prevent the choking up The drying-cylinder A may be made of cast or sheet metal of any required diameter, and of such length as is best adapted or'the purposes for which it is to be used. The steam for heating the cylinder is let in through the hollow pipe B, which forms one of the journals for the cylinder to rotate on; and the water formed by the condensation of the steam in the cylinder is ejected or drawn otf through the nozzle or pipe O, which forms the journal for the other end of the cylinder. The cylindrical shell or outside A is supported and held from expanding or bilging by the use of cylindrical or annular ribs of T-iron, a a a, placed at such intervals on the inside as may be required; the number of them being governed by the length and diameter of the cylinder. The T-irons a. a c divide the interior of the cylinder A into a series of compartments, D D, in which the water collects from the condensed steam. These compartments are provided each with one or more buckets or troughs, d d, secured obliquely on the inside of the shell of the cylinder, with an opening, e, through the partition b, made by the ribs of the vT-iron a. lThe number of ,these troughsin each division will be governed by the size of the cylinder, so that a continuous ilow of Water from the condensed steam from one apartment to another will be toward the outlet or ejection pipe O. These troughs or buckets d d are made right and left, as shown in Figs. 1 and 2, so that the water will be discharged from the cylinder when rotated in either direction. To the bucket d in the last division D is attached a bent tube, F, connecting it With the hollow journal or eduction-pipe C.

YThere are other forms of troughs, and Various positions in which they may be placed within the cylinder so that they will discharge the condensed steam, but they are regarded as modifications of my invention 5 for instance, instead ofthe Water from the troughs d d being conducted through an opening in the partitions b b of the T-irons, the troughs or buckets may be arranged to discharge the Water over 'the inner edge of the ribs or partitions by raising the delivery-ends over them to pass the Water from one division to another; or other similar and equivalent devices may be arranged to effect the same result.

In constructing the troughs or buckets I do not eonne myself to the precise form or shapes delineated in the drawing, as they may be varied Without departing from the principles of my invention.

Vhat I claim as of my invention, and desire to secure by Letters Patent, is-

1. The arrangement of the troughs or buckets d 0l on the inner surface of a steanrdrying cylinder, they being Xed obliquely to the axis of the cylinder in such manner as to drain the condensed steam from one section to another until the Water is al1 discharged from the cylinder, as herein shown and setforth.

V2. VThe combination of the T-iron support- WILLIAM CARR COLLIER.
